Ontogeny and Marginal Growth in the Leaf of Eubrachion ambiguum
Department of Botany, University of Delhi Delhi 7, India
Accepted: 30 December 1968
Marginal growth in the leaf of Eubrachion ambiguum, a viscaceous hemiparasite, has been investigated. This growth is accomplished by the marginal meristem comprising the marginal initials alone as has been described earlier by Hara (1957) in Daphne odora. To the best of the author's knowledge the present communication is the second report of such a type of marginal growth in the dicotyledons.
Phylogenetically, at least in Eubrachion ambiguum, it probably represents a reduced rather than a primitive feature.
